What is the broadcast address for Ethernet?

What is the broadcast address for Ethernet?

The Ethernet broadcast address is distinguished by having all of its bits set to 1. As such, its MAC address is the hexadecimal value of FF:FF:FF:FF:FF:FF. This address is used to transmit data to all of the hosts on the local subnet.

What does the MAC address FF FF FF FF FF FF indicate?

The MAC address used for broadcast (broadcast MAC address) is ff:ff:ff:ff:ff:ff. Broadcast MAC address is a MAC address consisting of all binary 1s. Broadcast is “one to all” type of communication. In other words; “send once receive all”.

Why IPv6 does not use broadcast?

In IPv6, there’s no longer any broadcast – There’s only multicast, unicast and anycast. In IPv6 all nodes are required to support multicast. Without multicast, many services that you need will simply not work. There’s a constant hum from the network on the multicast channels.

What is wildcard mask in OSPF?

A wildcard mask is a mask of bits that indicates which parts of an IP address are available for examination. In the Cisco IOS, they are used in several places, for example: To indicate the size of a network or subnet for some routing protocols, such as OSPF.

What is the MAC address FFFF FFFF FFFF used for?

ffff. ffff , this is the special reserved MAC address indicating a broadcast frame. This is what makes an ARP Request a broadcast. Had Host A chosen to send this frame using a specific host’s MAC address in the destination, then the ARP request would have been unicast.

What is the multicast MAC address?

The multicast MAC address is a special value that begins with 01-00-5E in hexadecimal. The remaining portion of the multicast MAC address is created by converting the lower 23 bits of the IP multicast group address into 6 hexadecimal characters.

Why is subnet mask 255?

A subnet mask is a 32-bit number created by setting host bits to all 0s and setting network bits to all 1s. In this way, the subnet mask separates the IP address into the network and host addresses. The “255” address is always assigned to a broadcast address, and the “0” address is always assigned to a network address.

What is the .255 address used for?

The 255 address (in binary notation, a host address of all ones) is used to broadcast a message to every host on a network. Just remember that the first and last address in any network or subnet can’t be assigned to any individual host. You should now be able to give IP addresses to 254 hosts.
